How about some DIY pedal upgrades/maintenance...
Speedplay makes highly reliable pedals for road or mountain bike. They use several bearings for each pedal. Like any other bearings, they need some care from time-to-time. Rebuilding and maintaining your speedplay road pedals are really easy to do. Speedplay made their pedals user serviceable however, you can always ask your local bike shop to do this for you.
Maintaining the performance of your cleats only takes a few seconds. It takes a drop or 2 of dry PTFE lube every 2-3 rides is all there is to do. The dry PTFE lube facilitates easy entry and release. It also extends the life of the pedal and cleats. It is dry so it does not attract dirt.
On the other hand, Speedplay pedal maintenance requires a special speedplay grease gun and SP-lube insert. It only needs a squirt of SP-lube every 1000 miles. The SP-lube/grease gun combination flushes out the old grease from the bearings replacing it with clean grease. Greasing your pedal will surely bring more miles of use to them.
Finally, when it is time to replace the bearings on your Speedplay pedals, there exist several aftermarket bearing kit for them. I have the Ti Zero series road pedals as an example. Boca Bearings has hybrid ceramic bearing kit for the Ti Zero pedals. I am sure other companies followed suit. The Boca ceramic hybrid kit comes with 6-bearings, 3-for each pedals. Instructions can be found at Speedplay site or have your local bike shop do the bearing replacement for you.
Here are some pictures of the rebuild/upgrade that I did with my Speedplay Ti Zero pedals:

6-bearing kit
Some heat to be applied to the T-20 screw. This will break the bond and makes for easy removal of the screw
Pedals removed, inspect the surface of the spindles. Looking good here. Clean and apply some grease. Make sure to clean the O-ring seals.
Body removed
A sharp pointer can remove the c-clip. This holds the bearings in place and needs to be removed for the bearings to come out!
Other side of the body houses the needle bearings. This is the one closest to the cranks.
C-clip removed. Note the size of the replacement bearings.
Some tools that I used for the bearing upgrade
Bearings removed. Clean pedal body and put new bearings in the body.
Important:
Note that size of the bearings. Make sure you install the correct size bearings. If the pedals developed a play, that means the bearings were not installed in the correct order.
Finally, install the C-clip into the groove and make sure you use a Loctite on the T-20 screw. Install the dust cover and small grease port screw.
Done!
Note: I did not upgrade the needle bearings. According to Speedplay, they pressed and bonded the needle bearing into the pedal body. Removing it may cause damage to the pedal body.
